A
Fair Three-sided Die
In a probability/statistics setting,
the term "fair" usually refers to an experiment or process with
equally likely basic outcomes.
Suppose we have a fair, three-sided die
- for our purposes, we have a fair, six sided die with two "1" faces,
two "2" faces and two "3" faces.
We can summarize this die in a simple
table:
|
Face Value |
Number of Faces on Die |
Odds/Proportion for Face Value |
|
1 |
2 |
2:6 or (2/6) or (1/3) or 33.33% |
|
2 |

2:6 or (2/6) or (1/3) or 33.33% |
|

2:6 or (2/6) or (1/3) or 33.33% |

6:6 or (6/6) or 1 or 100% |
In long runs of tosses of our die, approximately 2 out of every 6 tosses will show the
"1" face.
In long runs of tosses of our die, approximately 2 out of every 6 tosses will show the
"2" face.
In long runs of tosses of our die, approximately 2 out of every 6 tosses will show the
"3" face.
